In 2012, then US secretary of state Hillary Clinton opened the 2nd US-Lower Mekong Ministerial Meeting in Siem Reap. She admitted the US‘s mistakes in infrastructure projects on the Mississippi River. To „avoid the same mistakes“, Ms Clinton offered contributions for impact assessments on proposed hydropower dams through the so-called Mississippi-Mekong Partnership which was to serve as a mechanism to promote cooperation and development in six pillars: agriculture and food security, connectivity, education, energy security, environment and water, and health.
